When it comes to construction, steel reinforcements play a pivotal role in ensuring the structural integrity of buildings. In Nigeria, these crucial components, often referred to as iron rods, come in various sizes and types, with the Hot Rolled Deformed Bars being the most widely used for enhancing concrete tensile strength in beams and columns.
Types of Steel Bars:
Understanding the types of steel bars is essential for any construction project. The four main types used for load-bearing purposes are Cold Worked Steel, Prestressing Steel, Hot Rolled Deformed Bars, and Mild Steel Plain Bars. In Nigeria, Hot Rolled Deformed Bars, commonly known as iron rods, are the go-to choice for their superior tensile strength.
Choosing the Right Size:
For small to medium-scale projects, 6mm, 8mm, and 10mm bar sizes are cost-effective without compromising structural integrity. However, large-scale engineering constructions like bridges may require higher diameter bars to maintain stability over extensive lengths.
Current Prices:
- 6 mm: ₦1,200 per piece
- 8 mm: ₦2,100 per piece
- 10 mm: ₦3,300 per piece
- 12 mm: ₦4,800 per piece
- 16 mm: ₦8,500 per piece
- 20 mm: ₦13,000 per piece
- 25 mm: ₦21,000 per piece
- 30 mm: ₦30,500 per piece
Standard Length of Iron Rods:
The standard sale length of iron rods in the Nigerian market is 12 meters, catering to both low and full gauges. For instance, a ton of Y16 reinforcement bars contains 52 pieces of 12-meter length steel bars.
Stirrup Rebar Costs:
Stirrups, essential for holding steel bars together at intervals, come in smaller diameters. Their current price per unit is below ₦900.
